Feasibility study for the Tonawanda site, Tonawanda, New York.

摘要

From 1942 to 1946, portions of the Linde property and buildings in the Town of Tonawanda, New York, were used for separation of uranium ores. These processing activities, conducted under a Manhattan Engineer District (MED) contract, resulted in radioactive contamination of portions of the property and buildings. Subsequent disposal and relocation of processing wastes from the Linde property resulted in radioactive contamination of three nearby properties in the Town of Tonawanda: the Ashland 1 property, the Seaway property, and the Ashland 2 property. Together these four properties are referred to as the Tonawanda site. DOE is conducting a remedial investigation/feasibility study/proposed plan-environmental impact statement (RI/FS/PP-EIS) process for the Tonawanda site in accordance with procedures developed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and National Environmental Policy Act (NEPA). The RI report, a baseline risk assessment (BRA), and the FS are the primary evaluation documents prepared by DOE to summarize the findings of the integrated RI/FS/PP-EIS process. The RI report summarizes the findings of activities conducted at the Tonawanda site to determine the nature, extent, and potential for migration of the radioactive and associated chemical contamination resulting from MED operations. The BRA presents the findings of an assessment to determine the human health and ecological risks posed by the presence of radioactive and associated chemical contamination. The FS report identifies, develops, and evaluates remedial action alternatives for the site based on the nature and extent of contamination documented in the RI report. The FS report also evaluates the potential environmental consequences of the various remedial action alternatives identified.
